You mean between {du`u .... kei}? That's a syntactic bridi, and
that has no bearing on the properties of x1.

Are you talking about syntactic bridi or semantic bridi?

At any rate, it is the case that the text between {du`u...kei}
expresses a semantic bridi.

You have repeatedly asserted this, even though I have already
explained why it is false.

It is not arguable. You are correct. You are just missing the
point.

Look, it works like this.

  T is text between {du`u} and {kei}.
  P is proposition expressed by T.
  x1 = P
  x2 = some text that expresses P.

If T includes Q-kau, then you cannot know what P is unless you
know more about the larger sentence, S, containing T. Properties
of P are dependent on properties of S. If you vary S, then
P may alter, or there may even be no P at all.

Right.

I'm not clear about what you mean.
